Embedded and hobbyist hardware specialist LILYGO has launched a new version of its T-Watch wearable development platform dubbed the T-Watch Ultra \u2014 featuring an AMOLED display, integrated LoRa transceiver, and an Espressif ESP32-S3 microcontroller.<\/p>\n
LILYGO is no stranger to watch-style wearables: the company released its original TTGO T-Watch back in 2019, before updating it a year later with a slimline redesign dubbed the T-Watch-2020. A year after that, the T-Watch 2020 V3 was released, adding a microphone to the design \u2014 but the new T-Watch Ultra is a considerable upgrade over everything that has come before.<\/p>\n

The new smartwatch development platform, brought to our attention by Linux Gizmos<\/a>, is based on the more powerful Espressif ESP32-S3, giving it a pair of Tensilica Xtensa LX7 cores running at up to 240MHz plus 8MB of pseudo-static RAM (PSRAM) and 16MB of quad-SPI program flash, with a mciroSD Card slot for storage expansion. This is hidden behind the watch’s display, a 2.06″ AMOLED touchscreen with a 410\u00d7502 resolution \u2014 both bigger and brighter than the 1.54″ LCD touchscreen of the T-Watch-2020 V3.<\/p>\n There’s been a big upgrade on the connectivity front, too. The Bluetooth 5.0 Low Energy and single-band 802.11b\/g\/n Wi-Fi radios of the earlier watches are still intact, but LILYGO has chosen to add a Semtech SX1262 LoRa transceiver \u2014 meaning, should the firmware be ported to the platform, the potential for the watch to be used as a node on the Meshtastic community-driven mesh and other LoRa-based networks. There’s also a u-blox MIA-M10Q Global Navigation Satellite System (GNSS) receiver and a six-axis Bosch BHI260AP inertial measurement unit with integrated machine learning core.<\/p>\n The watch is surprisingly compact, given the amount of hardware LILYGO has crammed into its housing. (\ud83d\udcf7: LILYGO)<\/p>\n Other features include a microphone, amplified speaker, haptic vibration motor, Near Field Communication (NFC) transceiver, and \u2014 as you’d hope to find in a device that is, when all is said and done, a watch \u2014 a real-time clock. An internal 1,100mAh battery keeps the device ticking, with a USB Type-C connector for charging and data; programming is supported via the Arduino IDE, MicroPython, and Espressif’s own ESP-IDF.<\/p>\n The T-Watch Ultra is listed on the LILYGO website<\/a> now at $78.32, though at the time of writing was showing as out-of-stock; more information is available on the product’s GitHub page<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"Embedded and hobbyist hardware specialist LILYGO has launched a new version of its T-Watch wearable development platform dubbed…\n","protected":false},"author":2,"featured_media":287865,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[3160],"tags":[1685,53,16,15],"class_list":{"0":"post-287864","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-gadgets","8":"tag-gadgets","9":"tag-technology","10":"tag-uk","11":"tag-united-kingdom"},"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@uk\/114908151653947771","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/posts\/287864","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/comments?post=287864"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/posts\/287864\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/media\/287865"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/media?parent=287864"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/categories?post=287864"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/tags?post=287864"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
